DIsrENsING-MACHINE.

Application filed October 14, 1919.

To all whom itma y com c/en e it known that I, NVILLIAM l/V. STEWART, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented'new and useful, Improvements in Dispensing-Machines, of which the following is a specification.

This invention relates to improvements in coin-controlled dispensing devices for dis- 1plegnsing liquids such as cologne and the One of the objects of the invention is to provide a pumping device operated by a vertically movable said part stationary until the coin is introduced.

Another object of the invention is to provide means for causing the coin to release the locking means so that the pump mechanism may be actuated to force the liquid from its container.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of the invention;

Fig. 2 is a section on line 2-2'of Fig. 1; Fig. 3 is an enlarged view partly in section, showin the operation of the dogs for controlling t e plunger;

Fig. 4 is a view of the plunger;

ig. 5 is a view of the coin dispensing member;

Figs. 6 and 7 are detailed e Fig. 8 is a detailed view of the pump device. I

Fig. 9 is a view of the other dog.

In these views 1 indicates a case which is composed of wood and glass, as shown, and is provided with a drawer 2 at its lower part for receiving the coins. The case contains the containers 3 for the liquid to be vended and these containers are each provided with the pump mechanism 4. Such mechanism consists of the barrel 5 having its upper end engaging the stopper 6 for the container.

part with means for holding Patented July 20, 1920. Serial No. 330,648.

The lower end of the with an enlarged chamber 7, the inlet end of which is closed by the ball valve 8. A piston 9 is located in the barrel and the rod 10 thereof passes through a suitable packing gland 11 on the stopper. The outlet pipe 12 has its lower end connected with the chamber 7 and its upper end passing through the stopper and bent at right angles with its end passing through an opening in the glass front of the case. This pipe 12 is provlded with a valve 13 for preventing backward flow of the liquid. It will thus be seen that when the piston is raised the liquid in the container will be sucked into the chamber and barrel and when the piston is lowered the valve 8 will prevent the liquid from returning to the container so that the liquid must pass into the outlet pipe 12 and thus be forced through the open end of the same. This end may be provided with a nozzle so that the liquid will be delivered in spray form .or it will be so formed as to deliver the liquid in the fine stream.

he upper end of the piston rod 10 is connected with a plunger 14 which is vertically movable in a guide 15 connected with the upper portion of the coin chute 16. This coin chute passes through the top of the case as does also the guide and the upper 'end of the plunger is bent at right angles to provide a finger-engaging part 17. Outside of the case the coin chute is provided with a coinreceiving mouth 18 and said chute, within the case is provided with an inclined portion 19 to carry the coin to one side of the contalner and then the chute passes downwardly to deliver the coin into the drawer 2.

In order to cause the plunger to operate the pump, said plunger must first be raised to draw the liquid into the pump barrel and then lowered to force the. liquid out of the pump. I provide means for locking the plunger in its lowest position and such means consist of a springcontrolled dog 20 having its right angular extending tooth 21 engaging the rack teeth 22 formed on one edge of the plunger. These teeth are so formed that the dog will engage them and prevent the plunger from being raised but the dog will slip over the teeth when the plunger is being lowered. I form another rack 23 on the opposite edge of the plunger. but these teeth are oppositely arranged to the teeth of the other rack and such teeth are adapted to be engaged by a dog 24 pivbarrel is provided otally connected to a part of the chute. This dog is held in contact with the teeth by a spring 25. This dog is normally held out of engagement with the teeth of the rack by means of a dog 26, pivotally part of the chute and the spring 27 of which is stronger than the'spring 25. This dog 26 is provided with a laterally projectingtooth 28 which engages the lower end of the dog ,24 so as, to hold said dog awayfromi the teeth owing to the fact that the spring 2? is stronger than the spring 25. The plunger also'carries a spring-controlled dog 29 which is. adapted to engage the coin onthe down- .ward movementof the plunger. The top of the coin chute isopen and-receives a pusher member 3O,v the top ofwhichis cov- .and this member is also sprlng 34 for engaging the coin. V r I It Wlll be seen that, when a co n is de- 7 suck a portion of the liquid into The dog 24 will engage the rack teeth 23 and thuspredownwardly 'ered'by a plate 31 provided with aneXten- .sion to form a hand hold. This member 30 is provided with a laterally extending lug'32 which opens into the mouth 18 of the chute provided witha posited into the mouth 8 and the member 30 raised, said coin will pass through the opening 831and drop ontothe dogs 2t 'and26. The lug 32 acts as a stop for the member- 30. The said with a smooth portion of the plunger '50 as to permit .the said plunger to be moved aslight distance in order'to permit the dog 29.15 engage with the coin and push thesame over the dogsto release thesame, thus permitting the dog 26 to move the dog 24 into inoperative position SQttliilt theplunger may be forcedto its lowestposition,,the dog 20 riding over the rack teeth 22. Thus the liquid will be discharged from thepump mechanism and when the plunger has reached its lowest position the dog 20 I will preventit frombeing raised again.

o I provide a stopper 35 on the end of the plunger for preventing its upward movement, and I alsoprovide a lock-ingstrap 343 which has one end secured to the inclined mounted on a risin 'a' case member 30 is then pushed down-- wardly to force'thecoin onthe dogs,'thus .forcing the dog 20 out of engagement'with the rack teeth andv releasing the dog2t from part of the chute and its other end extending over theostopper and container mouth to prevent the stopper-and container being moved from the receptacle.

The drawing shows the case provided with a pair of containers, but it will, of course,

be understood that one or more containers may be placed in the case.

It is thought trom the foregoing description that the advantages and novel teaparent.

I desire. it to be understood' that I may .make changes in the construction and in the combination and arrangement of the several parts, provided that such; changes fall within the scope of the appended claims;
